What is the minimum recovery rest period required?

• A. 24 hours including 1 night
• B. 36 hours including 2 nights
• C. 48 hours including 2 nights
• D. 72 hours including 3 nights

Answer: (B)

Recovery rest is the mandatory pause after a duty that lets fatigue and sleep debt fade and the body reset. The minimum required is 36 hours including two nights. This structure gives two full sleep opportunities, helping the body realign its circadian rhythm after irregular hours or crossing time zones and ensuring you’re ready for the next duty. Shorter rest, like 24 hours with one night, wouldn’t provide enough recovery, while longer rests such as 48 or 72 hours are beyond the minimum and can unduly constrain schedules.
